I want to update the AT version on my ESP01 from 1.1.0.0 to 2.1.0 so I can change the baud rate of the board. I downloaded the Flash Download Tool, 3.4.9, and attempted to start it. Having used a previous version, I was looking for the UI to appear. Instead, the console displays a lot of text and a couple of errors.
The console starts with "wxPyDeprecationWarning: Using deprecated class PySimpleApp.
After selecting the ESP8266 Download Tool button, the last line in the console reads:
File "main.py", line 72, in ShowDownLoadToolEsp8266 with some indication that it could not connect to my powered ESP01. Thoughts?
